CHOMARAT will present its latest innovations at JEC

At the 2018 JEC World trade show CHOMARAT (Hall 5A / Stand J42) unveils its new multiaxial NCF reinforcement for thermoplastics, plus an innovative (UD) carbon reinforcement for wind energy.

CHOMARAT, the composite reinforcement specialist group, is launching its multiaxial glass NCF for thermoplastic composites. The unique patented stitching yarn used can withstand processing temperatures to 400°C, making it an innovative industrial solution for thermoplastic composites and an alternative to the woven reinforcements used especially in the automotive sector. For the first time, CHOMARAT is also exhibiting a unidirectional carbon NCF reinforcement that is adapted to the productivity and performance requirements in the wind energy sector.

Thanks to a unique patented stitching yarn, the glass NCF reinforcement (G- PLYTM) developed by CHOMARAT offers new possibilities in thermoplastic RTM and organosheet processes. “This is an especially innovative solution, utilizing stitching yarns that are compatible with processing temperatures to 400°C. These multiaxials improve the performance and provide a lot of construction freedom in terms of fibre orientation. These new design possibilities contribute to structural optimization. The quest for more lightweight vehicles, shorter cycle times and lower cost is a major issue for all builders,” explains CHOMARAT Automotive Market Manager Francisco De Oliveira.

This new heat-stable G-PLYTM reinforcement can withstand very high processing temperatures without deformation and provides optimal mechanical performance.

A CARBON UD TO REINFORCE EXTRA-THICK WIND TURBINE STRUCTURES

For the first time, CHOMARAT is exhibiting an infusion-moulded laminate made with 150 plies of its new unidirectional carbon C-PLYTM. This 600g/m2, high-permeability NCF can be used to create extra-thick structures, in particular the wind-turbine blade stiffeners, or spar caps. “Cost reduction is the challenge in the wind energy industry. Increasing the blade length by incorporating carbon stiffeners increases power, and so it also lowers the cost of the energy,” says CHOMARAT Wind Energy Market Manager Raphaël PLEYNET. The carbon UD developed by CHOMARAT provides a solution to achieve the goal to optimize the weight/power ratio. The UD’s high permeability reduces cycle times and lowers the blade production costs.

Professor Sung Ha from the University of Hanyang will give a conference on composite challenges in the wind energy sector at 11:30 am on Wednesday, 7 March 2018 at JEC World.
